Abstract
"VáLVULA DE ENTRADA DE AR PARA COMPRESSOR DE AR EM ESPIRAL GIRATóRIO SEM óLEO". é revelada uma montagem de válvula de entrada de ar para um compressor em espiral giratório. O compressor em espiral giratório inclui elementos em espiral estacionário e em órbita que são interengrazados e encaixados para formar pelo menos uma cavidade de compressão em espiral entre os mesmos, um mecanismo de acionamento aciona o elemento em espiral em órbita em uma órbita em torno do elemento em espiral estacionário, e um dispositivo de mancal anti-rotação mantém o elemento em espiral em órbita substancialmente não rotacional com relação ao elemento em espiral estacionário. A montagem de válvula de entrada de ar fornece um gás não comprimido (por exemplo, ar ambiente) ao aparelho de compressão e evita rotação para trás do elemento em espiral em órbita quando termina a energia para o mecanismo de acionamento. A montagem de válvula de entrada de ar inclui um pistão de válvula posicionado dentro de um canal de entrada de ar conduzindo à região de sucção do compressor em espiral giratório, o pistão de válvula tendo uma primeira posição que bloqueia o canal de entrada de ar e uma segunda posição desbloqueando o canal de entrada de ar. Um elemento de haste de válvula é conectado a um alojamento de válvula, o alojamento de válvula encerra uma cavidade de válvula onde o pistão de válvula é localizado, o pistão de válvula atua em conjunto com uma sede de válvula formada no alojamento de válvula, e superfícies de parada são fornecidas no pistão de válvula e haste de válvula para limitar movimento do pistão de válvula em direção à região de sucção do compressor em espiral giratório."AIR INLET VALVE FOR ROTARY SPIRAL AIR COMPRESSOR WITHOUT OIL". an air inlet valve assembly for a rotary spiral compressor is revealed. The rotary spiral compressor includes stationary and orbiting spiral elements that are interlocked and interlocked to form at least one spiral compression cavity between them, a drive mechanism drives the spiral element in orbit in an orbit around the element stationary spiral, and an anti-rotation bearing device keeps the spiral element in substantially non-rotational orbit with respect to the stationary spiral element. The air inlet valve assembly provides uncompressed gas (eg ambient air) to the compression apparatus and prevents rotation backwards from the orbiting spiral element when power to the drive mechanism ends. The air inlet valve assembly includes a valve piston positioned within an air inlet channel leading to the suction region of the rotating spiral compressor, the valve piston having a first position that blocks the air inlet channel and a second position unlocking the air inlet channel. A valve stem element is connected to a valve housing, the valve housing encloses a valve cavity where the valve piston is located, the valve piston acts in conjunction with a valve seat formed in the valve housing, and Stop surfaces are provided on the valve piston and valve stem to limit movement of the valve piston towards the suction region of the rotating spiral compressor.
